SHEET-MATERIAL-MEASUEING DEVICE,

Applicants median@ ia, 192s. semi No. 646,002,

To all whom t may concern.'

Be it known that I, EsNEs'r E. Monsn, a citizen of the United States, residing at, llfoburn, in the countyv of llliddlesex and State of Massachusetts, have invented new and useful Improvements in Sheet-Materiallvfeasuring Devices, of which the following is aspeciication.,

This invention relates to an improved measuring device for measuring the thickness of sheet material.

rThe object of the invention is to provide a measuring device for measuring the thickness of sheet material, such as, leather, fabric, paper, etc.

Another object of the invention is to provide a measuring device of the character set forth, which will operate accurately and be of simple construction.

The invention consists in the combination and arrangement of parts set forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings Figure 1 is a side elevation of my improved measuring device.

Fig. 2 is a plan view of the same, broken away.

Like numerals refer to like partsv in the views of the drawings.

In the drawings, 5 is a U-shaped frame consisting of two arms 6 and 7 connected together by a curved portion 8e A station ary contact member 9 has' screw-threaded engagement with the forward end 10 of the arm 6, whereby said stationary contact member may be adjusted vertically and when so adjusted is held in position by a clamp screw 11. The forward end 10 of the arm l6 is split at 12 which, together with the clamp screw 11 constitutes a clamp;

A slidable contact member l13 consisting of a tube 13, one end 14 of which is closed, the other end being provided with a flange 15 is slidably mounted in the forward end 16 of the arm 7 and isoppositely disposed and in alignment with the stationary contactmember 9. A screw 17 in the end 16 of the arm 7 projects into a slot 18 in the tube 13 and prevents said tube from rotatspring 19 is located within the tube 13 and held therein by a rotary shaft 2O which extends into the upper end of saidtube, the other end 141-. of which is closed. The rotary shaft 20 is journaled at its upper end in a sleeve 21fwhichis fast to a bracket 22`,^which l in turn is fast yto the arm 7. A dial 23 is fast to the upper surface of the bracket 22 and located immediately above said dial is an indicator 241 fast to the upper end of the rotary shaft 20. A pin 25`in the flange 15 of the tube 13 projects into a helical groove 26 in said rotary shaft and when said tube is caused to move upwardly or downwardly a rotary motion is 'imparted' thereby to the shaft. f

A lever 27 is pivotedy yat 28 to ears 29 on the arm 7 the forward end of said lever 2,7 being forked at'30 and pivotally connected to the tube 13'at the flange 15`by pins 31 ywhich extend into elongated slots 32 in the forked portion 30 of the lever 27. A handle 33 is formed on the opposite end of the lever 27 and another handle 34- is formed on the curved portionS kof the U-shaped frame 5 and by 'grasping these two handles 33 and 34 and causing them to move towardy each other, an upward movement will be imparted to the tube 13 and'when this pressure is released the tube 13 will be caused to ree turn to its normal position by the spring 19.

The .arm 6 of the U-shaped'meinber 5is provided with a base 35 for convenience when the device is being used on atable or bench; j

The general operation of my improved measuring device hereinbefore specincally described is as follows :h

The handles and 34 are grasped in the hand and a squeezing pressure applied thereto causing the lever 27 to rock thus moving the forked end 30 upwardly andy with it the tube 13.` This upward movement of the tube 13 causes the rotary shaft'20 to rotate through the medium of the pin 25 and helical groove 26. With the device in this position` a piece of sheet material 36 is inserted between the stationary contact member 9 and the slidable contact member 13. The pressure on the handles 33 and 34 isr then released and the slidable contact member 13 will be caused to return to the position illustrated in Figure 1 by the spring 19, the indicator 24 at this time having come to a rest will indicate on the dial 23 the thickness of the sheet material 36 which is then yclamped between the stationary contact member 9 and removable contact member 13.

I claim :M

l`A 'A device for measuring the thickness of sheet material having, in combination, a stationary contact member, a slidable contact member oppositely disposed thereto, a.

frame upon which said contact members are mounted, means to impart a reciprocatory motion to said slidable contact member, a shaft provided with a helical groove and rotatably mounted on said frame, an indicator fast thereto and a projection on said slidable contact member projecting into said helical groove, whereby when said sliding contact member is moved, said shaft will be rotated.

2. A device for measuring the thickness of sheet material having, inl combination, a stationary contactl member, a sidable contact member oppositely disposed thereto, a frame upon which said contact members are mounted, a spring operative to move said slidingcontact member toward said stationary contact member, a lever to move said sliding contact member away from said stationary contact member, a shaft provided with a helical groove and rotatably mounted on saidiframe, an indicator fast thereto and a projection on said slidable contact member projecting into said helical groove whereby'when said sliding contact member is moved, said shaft will be rotated.

3. A device for measuring the thickness of sheet material having, in combination, a stationary contact member, a slidable contact member oppositely disposed thereto and embodying a tube, a spring in said tube, a shaft rprovided with a helical groove and rotatably mounted on said frame, one end projecting into said tube and engaging said spring, an indicator fast to the other end vofv said shaft, a projection on said tube projecting into said helical groove and means including said spring to move said tube longitudinally of said shaft whereby said shaft will be rotated.

Il, A device for measuring the thickness of sheet material having, in combination, a U-shaped frame, a stationary contact member on one arm of said U-shaped frame, another cont-act member slidably mounted on the other arm of said frame and oppositely,

disposed to said stationary contact member,

means to impart a reciprocatory motion to said slidable contact member, a shaft provided vvith a helical groove and rotatably mounted on said frame, an indicator fast thereto and a projection on said slidable contact member projecting into said helical groove whereby wheny said sliding contact member is moved, said shaft will be rotatedu 5. A device for measuring the thickness of sheet material having, in combination, a U-shaped frame, a stationary contact member on one arm of said U-shaped frame, another contact member slidably mounted on the other arm of said frame and oppositely disposed to said stationary contact member, a handle on said frame projecting nearwardly therefrom, a spring operative to move said sliding contact member toward said stationary contact member, a lever adapted to move said sliding contact member away from said stationary contact member and projecting rearwardly therefrom and above said handle, a shaft provided with a helical groove and rotatably mount ed on saidframe, an indicator fast thereto and a projection on saidslidable cont-act member projecting into said helical groove whereby when said sliding contact member is moved, said shaft will be rotated.

6.
